In 2021, the LHCb Collaboration observed three new \(\varXi _{b}\) baryonic states: \(\varXi _{b}(6227)\) , \(\varXi _{b}(6327)\) , and \(\varXi _{b}(6333)\) . The spin-parity of these states remains undetermined. This study examines the mass spectra of the baryon. To achieve this aim, we utilize the framework of the relativistic flux tube model, incorporating a heavy bottom quark and a light diquark representation of baryons. We incorporate the spin-dependent interactions in the limit of heavy quark symmetry. The results obtained align well with the existing experimental masses. The findings indicate that the \(\varXi _{b}(6227)\) is a viable candidate for the P-wave baryon with \(J^P\) value \(\frac{1}{2}^{-}\) or \(\frac{3}{2}^{-}\) . Additionally, the baryons \(\varXi _{b}(6327)\) and \(\varXi _{b}(6333)\) can be effectively understood as P-wave baryons with \(J^P\) values \(\frac{3}{2}^{-}\) and \(\frac{5}{2}^{-}\) , respectively. This study can contribute to constructing the highly excited states of the baryonic family.
